📍 Geographic Location of Mellau
Geographic Overview and Administrative Jurisdiction
The Austrian area code 05518 (international format +43 5518) is a geographic National Destination Code (NDC) assigned to the Bregenzerwald region in the westernmost federal state of Vorarlberg. Specifically, it serves the municipality of Mellau and its immediate surroundings, including the adjacent villages of Schnepfau and Reuthe. The code is administered under the national numbering plan of the Rundfunk und Telekom Regulierungs-GmbH (RTR), which follows ITU-T E.164 recommendations for international dialing.
Coverage Area and Primary Localities
The 05518 prefix covers a high-alpine valley area at the foot of the Kanisfluh mountain range. Subscriber lines are primarily located within the political boundaries of Mellau (postal code 6881), with some rural extensions reaching nearby hamlets and agricultural zones. The region is known for tourism, and many second homes and guesthouses have fixed-line connections under this code. However, note that mobile numbers in Austria are non-geographic and never use 05518.
Dialing Formats and Instructions
For domestic callers within Austria, the national trunk prefix 0 must be dialed before the area code: 05518 12345 (where 12345 is the local subscriber number). For international callers, the Austrian country code +43 replaces the leading zero, and the area code is used without the trunk prefix: +43 5518 12345. When dialing from a mobile phone within Austria, the national format (05518) is required, as the plus sign is not necessary for domestic calls. If you are physically in Mellau and calling a local number, you may be able to use short-code dialing (7-digit local number) depending on your operator, but the standard national format is always safe.
Overlay and Numbering Considerations
As of the latest RTR updates, there is no overlay code for 05518, meaning the area code is unique for this geographic region. The local subscriber numbers are typically 5 to 7 digits long, resulting in a total national significant number (NSN) length of 9 to 11 digits when including the area code. No special tariffs apply to calling this code; it is treated as a standard geographic fixed-line call. For VoIP users, the same dialing rules apply, but ensure your provider routes calls to Austrian geographic numbers correctly.
